math - How does 4x4 matrix work in 3d graphic? -

I'm learning about 3D graphics and stumbling across the matrix, which I can not fully understand . I have 3D object, with topology, points in coordination system and ECS (object 4x4 matrix) ECS is:

  -1.1247455413666 E-32, 1.83690953073357 E-16, 1, -95, 1, 6.12303176911189 E-17, 0, 604, -6.12303176911189 E-17, 1, -1.83690953073357 E-16, 200.5, 0, 0, 0, 1,  

How is each row different with a comma? Are these translations vectors?

Rotation of the coordinate system from the upper left 3x3 block, the coordinates of the top 3 final columns give translation vector.

The general idea of ​​this Anne parametrication is to convert a polygon to

  [x, y, z, 1] ^ t  

Right from
